T0 aZZw/wm it may concern .Be it known that 1, JOHN S. BERRY, a citizen of the United States, residing at Norwood, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in lvVindows, of which the following is a specification. 7

My invention relates to. window sashes and fittings, enabling the same to be tilted forward to a horizontal position within the building for cleansing and other purposes; and its purpose is to provide eflicient means for this purpose, whereby the sashes when thus tilted forward are securely held in relation to their pivots until againrestored to vertical position in their guideways; also, in connection therewith, to provide a collapsible parting-strip and means for collapsing thesameautomatically by the sash in its downward movement; and to provide a combined mechanism for accomplishing the collapsing of the parting strip and the pivoting and locking of the sash by the movement of the sash itself.

To these ends my invention consistsin the mechanism hereinafter described.

Attached hereto and forming part hereof are drawings illustrative of my invention, to which, reference ismade for'better understanding of structural details. 7

In these: Figure 1 is a perspectiveview of a portion ofthe bottom and side of the windoW sill and easing showing parts of the structure embodying my invention attached in operative connection as hereinafter described, ready'to receive and control the action of the sash; Fig. 2 isfa face view, of the automatic sash retainer, in the position occupied when the sashis engaged and drawn to a horizontal positionin relation to the window frame; Fig. 3 is a detail ofthe structure showing the stud holder in relation to the inclined surface formed by the depressed tongue with the stud in its receded position; Fig. 4 is a perspective :view of the shoe, preferably employed to obviate wear and insure proper seating and engagement of the inner sash in the automatic pivot device; Figs. 5, 6 and 7 arejdetail views showing the structure of the operative parts and connections of the collapsible parting strip; Fig. 81s a perspective elevationof the collapsible parting stripin position with its operating device and pivot'connection. ready to be operated by the upper sash; and Fig.9 is a perspective ,view of a lower corner of, the

upper sash showing the engaging socket formed to pass over and engage the pivot shown in Fig. 8. y

Referring now to the drawingsA designates one of the automatic pivot-devices, two of which (right and left) are required for the inner sash to be attached to the window frame in the guideway between the parting strip andthe front beading (which is hinged or otherwise made removable to allow the sash to tilt inward. at the top). 7

Description of one of the automatic pivot devices will serve for both.

Its structural elements are, first, a base plate a securely fitted into the bottom of the guideway flush with its surface. It has a tongue a cut therein in an arc approximately concentric with a pivota as shown (Fig. 3),.and bent downward in a cavity of the wood beneath to form an inclined surface, for a purpose to be presently described. A second plate 6 of the form shown, is superimposed upon. the plate a on which it has sliding motion controlled by the pivot which holdsthe two plates together. The

plate 6 is perforated to receive and permit the play of a stud 6 attached to a leafspring holder 72 secured to the underside of the plate 6 as indicated by dotted lines (Fig. 2), and normally in the relative position shown in Fig. 3. The two plates being attached flush with the bottom surface of the guideway of the lower sash, in position shown in Fig. l, the spring holder 6 projects downward in and through plate a in the aperture formed by cutting the tongue a so that the stud is held inward beyond the normal bottom surface of the guideway, but when the plate 6 is moved to the position shown in Fig. 2, the spring holder 6 rides, up on the inclined surface of the tongue a and the stud b is forced outward through the aperture and projects beyond the guide surface of the plate 6 as shown in dotted lines in Fig. 3. V

vFor convenience and certainty of action the outer edge a of plate a is turned up as indicated. to form a stop for plate 12 The side edges of plate 6 are turned up in like manner as at b to form a receiving trough for the lower corners of the sash when depressed.

I preferto employ in addition a shoe C, (Fig. 4) fastened to each side of the sash atthe lower edges, and adapted to fit easily in the receiving trough just described.

a the sash being drawn in at the top remains This, should be noted, is a feature of convenience rather than of necessity, ,to'

prevent undue wear and also toinsure'the seating of the sash properly in the receiving trough. It is provided with turnedup sides 0 and a longitudinal slot 0 somewhat elongated so as to receive the projected stud 19 so as not to require a too close adjustment of the sash in its vertical position. Theoperation of this feature of my invention is as follows: The lower sash being brought to its lowest position, its lower edges at both sides enter between the side walls of the receiving trough 6 If it be desired to tilt the sash forward within the room, the front beadingd of the frame is loosed -(by means not shown herein) and seated in the troughs b at each side and draws said trough over upon its pivot a into the position shown in Fig. 2. In this change of position, the spring holder 6 is drawn in contact up the incline formed by the tongue a whereby the stud b is projected outward and into the socket at the side of the sash, so that the sash is securely held in relation to the'pivot a so long as the sash is out of the vertical position and upon'the return of the sash to a vertical position, the spring holder 6 rides down the inclined surface a and the stud b is drawn back to a non-engaging position. But with the upper sash the conditions are different by reason of the parting stripi E which should retain its position as a guide for both sashes except when both -sashes are let down, and it is desired 'totilt the upper sash forward at the same time with the lower sash.

To the end of making the lowering of the upper sash a means of removing the parting strip, preparatory to drawing said sash forward, I provide-a collapsible parting strip of metal, together with mechanism actuated by the sash in reaching its lowered position, to cause the collapse of the parting strip into the normal recess provided for it in the side-wall of the window casing.

The collapsible parting strip E consists of three elements, to-wit: a' trough-shaped strip 6 seated in a lining in the groove usually provided in the vertical 'side-walls v of the window-casing for the parting strip.

Next above this trough e andwithin and 1n contact with its side-walls, are two independent side strips 6 e", and above and be- 32 are loosely engaged by one or more arms or yokes Y common to all; the. three pivots thus holding the three elements of the 001- lapsible parting strip in a common adjustable relation as shown in Figs. 5, 6 and 7.

.70 The relative positions of the'yoke and the.

parts constitutingthe parting strip, inopen and closed positions of the parting are shown-in Figs. 6 and 7. Duplicates ofthe yo-keandpivotal connections are provided at given intervals in strip,

the length of the parting strip, whereby V the closing and opening movement of'the I parts is uniform throughout.

The closing. movement "is effected by a.

plate F pivotally carried uponxan outward prolongation of one ofjth'e pivots 10 near the bottom of the guideway. and lo- 'cated ad acent to the collapsible parting strip, as indicated in ,Fig. '1. The plate F 's pivotally connectedfat its rear extremity to a bracket 7 fastened to the bottom wall of the-guideway in such downwardly inclined position extending outward into the path of the sash, asshown in Fig. 8, by the force of a spring ft, arranged beneath the plate upon its pivotal connec-.

' relation that the plate'F is normally held in a tion; and,the plateF,'being-carriedupon an extensionof the pivot, p'fi of the collapsible parting strip, the parting strip is by the same spring pressure normally heldinits outward relation and operates' as guide for thesash. The sash inmoving downward and backward, presses the plates F downwardagainstthe force of thespring f and collapses the parting strip. The plate Fcarries upon its face a projecting stud f which, as the sash is depressed, enters an aperture g (Fig. 9), at the lower edge of the sash, and constitutes a pivot on which the sash may swing forward. The stud f and the socket g are formed to constitute a lock when the sash is tiltedforward so that the sash cannotibe released therefrom until it is again in vertical "position in its guideway.

The sprlng f it will be observed, notonly holds the collapsible partingstrip outward 1;. Q

in its operating position as a }guidefor"the sash, but also holds the plate F'fin'c'lose contact with the sash and thus insures the tingof the pivot stud f 'while the A p sash i 'tiltedforward. 1 q

The operation of the invention has-been already sufficiently described; and it will be seen that nothing is required of the servant orattendant but to loose' the front beadizo ing, tilt forward the lower (or inner) sash,

and while the same is thus positioned, tilt forward the upper (or outer) sash to'a like position above the -'-for-mer, and to restore the parts to original positions, "Thus all complication is avoided and the operations being extremely simple require 110 special skill. Moreover, the invention may be applied to the ordinary existing structures.

I claim as my invention and desire to secure by Letters Patent of the United States:

1. A pivoted shoe device for the purpose indicated, consisting of a plate adapted to be secured to the casing in the guideway of the sash, a shoe pivotally mounted thereon and adapted to receive and engage the sash, and a spring-mounted stud carried in and upon the shoe and adapted to be automatically projected through the shoe into a recess of the sash by the pivotal movement of the shoe and sash.

2. A tilting device for a sash embodying a plate adapted to be attached to the window casing; and having a portion depressed to form an inclined plane extending below its normal surface; a receiving shoe pivoted to said plate; a leaf spring'extending below the underside of the shoe; and a stud carried at the outer end of said spring; the arrangement being such that while normally the leaf-spring projects below and lies upon the inclined portion of the plate; a turn of the shoe by the tilting of the sash draws the spring up the inclined plane of the plate and projects the stud through the bottom of the shoe into the sash.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
